1. Also there is no way to set a starting angle then zero itI paid to get rid if the adverts, it works very well for my purposes.Works well in most common situations.
2. Recommend for use by hobbyists.Angle varies wildly and is very inaccurate on pixel 4It helps in my physics lab.
3. Could be worth buying just only gives you a few minutes to evaluate software.
4. I would rate it better if it wasn't nagging me Everytime I turned it on to buy it.
5. Just not enough time.Sensor fluctuates and can't get it to zero .
6. Very simple to use.
